How to use the grlc.gquery.count_query_results function in grlc

data = {'query': rewritten_query}

        glogger.debug('Sending HTTP request to SPARQL endpoint with params: {}'.format(data))
        glogger.debug('Sending HTTP request to SPARQL endpoint with headers: {}'.format(reqHeaders))
        glogger.debug('Sending HTTP request to SPARQL endpoint with auth: {}'.format(auth))
        response = requests.get(endpoint, params=data, headers=reqHeaders, auth=auth)
        glogger.debug('Response header from endpoint: ' + response.headers['Content-Type'])

        # Response headers
        resp = response.text
        headers['Content-Type'] = response.headers['Content-Type']

    # If the query is paginated, set link HTTP headers
    if pagination:
        # Get number of total results
        count = gquery.count_query_results(rewritten_query, endpoint)
        pageArg = requestArgs.get('page', None)
        headerLink = pageUtils.buildPaginationHeader(count, pagination, pageArg, requestUrl)
        headers['Link'] = headerLink

    if 'proto' in query_metadata:  # sparql transformer
        resp = SPARQLTransformer.post_process(json.loads(resp), query_metadata['proto'], query_metadata['opt'])

    headers['Server'] = 'grlc/' + grlc_version
    return resp, 200, headers
